Definitions

  • a catheter is commonly used to infuse fluids into vasculature of a patient.
  • the catheter may be used for infusing normal saline solution, various medicaments, or total parenteral nutrition.
  • the catheter may also be used for withdrawing blood from the patient.
  • the catheter may include an over-the-needle peripheral intravenous (“IV”) catheter.
  • IV peripheral intravenous
  • the catheter may be mounted over an introducer needle having a sharp distal tip.
  • the catheter and the introducer needle may be assembled so that the distal tip of the introducer needle extends beyond the distal tip of the catheter with the bevel of the needle facing up away from skin of the patient.
  • the catheter and introducer needle are generally inserted at a shallow angle through the skin into vasculature of the patient.
  • a clinician In order to verify proper placement of the introducer needle and/or the catheter in the blood vessel, a clinician generally confirms that there is “flashback” of blood in a flashback chamber of the catheter assembly. Once placement of the needle has been confirmed, the clinician may temporarily occlude flow in the vasculature and remove the needle, leaving the catheter in place for future blood withdrawal or fluid infusion.
  • an extension tube is integrated into and extends from a side port of a catheter adapter.
  • the extension tube may be used for blood draw and/or infusion.
  • multiple bandages are generally used to secure the extension tube to skin of the pediatric patient, which can make the pediatric patient uncomfortable and/or lead to removal or dislodgement of the integrated catheter assembly by the pediatric patient.
